Hunting with a T-Rex | Walking with Dinosaurs in HQ | BBC Earth

The mother Tyrannosaurus breaks her fast to provide a kill to feed her young. Even though they are small and vulnerable, the young T-Rex’s already have a fierce competitive streak. Broadcast in 1999, Walking with Dinosaurs set out to create the most accurate portrayal of prehistoric animals ever seen on the screen. Combining fact and informed speculation with cutting-edge computer graphics and animatronics effects, the series took two years to make.
